VALVE-OPERATING MECHANISM FOR INTERNAL-COMBUSTION EN GIN ES.

Specification of Letters Patent.

Patented Nov. 21, 1916.

Application filed December 31, 1914. Serial No. 879,914.

To all whom it may concern:

Be it known that I, HUGO C. Him, a subject of the Emperor of Germany, and a resident of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Valve-Operating Mechanism for Internal-Combustion Engines, of which the following is a full, clear, and exact descrip tion.

My invention has for its object to provide an internal combustion engine having two or more cylinders with a valve sleeve in each cylinder, spindles being j ournaled between the cylinders in bearings disposed at right angles tothe axes of the cylinders, .so that one sleeve will serve in connection with a spindle and gearing connecting the valve sleeves with the spindles to rotate the adjacent valve sleeves.

Another object of the invention is to provide means to rotate one of the spindles with the rotation of the engine.

Additional objects of the invention will appear in the following specification in which the preferred formof my invention is disclosed.

Certain features shown in the drawings and described inthe specification are claimed in my co-pending application having Serial No. 47,070.

In the drawings similar reference characters refer to similar parts in all the views in which- Figure 1 is an end view of the engine;

Fig. 2 is a sectional view on the line 22 of Fig. 4; Fig. 3 is a perspective view showing one of the valve sleeves; Fig. 4 is a side elevation with parts in section on the line M of Fig. 2. Fig. 5 is a plan view of Fig. 4; Fig. 6 is a sectional view showing the modified form of the invention; Fig. 7 is an end view of Fig. 6; Fig. 8 is a sectional view on the line 88 of Fig. 6; and Fig. 9 is a fragmentary sectional view illustrating the means for lubricating the piston and the beveled gear wheels which mesh with the gear teeth in the valve sleeves.

By referring to the drawings it will be seen that the engine is constructed with a plurality of cylinders 10 which are cast en bloc. As illustrated in Fig. 2 of the drawings, each of the cylinders 10 has a gas inlet 11, an air inlet 12 and an exhaust 13 which are commanded by the ports 14, 15, 16 and 17 in a sleeve 18, one of the sleeves 18 being disposed in each of the cylinders. The lower end of each of the sleeves 18 has gear teeth 19 with which mesh gears 20, 20 and 20 on the spindles 21, 21 and 21 ;'thes e spindles 21, 21 and 21 are disposed substantially at right angles with the axes of the cylinders 10 and are journaled in bear ings 22 in the supports 23 on which connecting portions 24 of the casting rest. The spindle 21 has. a hollow end 29 in whichv the end 2300f the crank 311s disposed, the other end 32 of the crank 21 being secured to the gear 20. This crank which rotates the gear 20 has its central portion 33 disposed in a slot 34 in a piston rod 35, the piston. rod being' articulated to'its piston 28 in the customary manner and being also articulated to the crank 36, for rotating the shaft 37 The crank 31 is rotated by the movement of the piston rod 35 for rotating the gear 20 and has been described. The gear 20 meshes with the gear teeth 19 on one of the valve sleeves for rotating the latter and the gear teeth on the valve sleeve mesh with the gear 20 for rotating the spindle 21 which has a gear 20 meshing with the gear teeth 19 on a valve sleeve in an adjacent cylinder. In this way valve sleeves in any desired number of cylinders may be rotated or if desired two or more cranks 31 may be provided for driving the gears 20 which may be connected for rotating a plurality of valve sleeves in the manner set forth. The sprocket wheels 50 on the spindles 21 may be used to drive a magneto or a pump.

1n the modified form of the invention and illustrated in Figs. 6, 7, 8 and 9 of the draw ings, gear wheels 40 mesh with the teeth 19 in the valve sleeves 18, the gear wheels 40 being mounted on spindles 41 journaled in bearings 42 in the cylinder supports 43. In this way the valve sleeves 18 are connected so that the rotation of one valve sleeve will through the gear teeth 19 thereon, the gear wheels 40 and the spindles 41 rotate the other valve sleeves 18. End gear wheels 40 are mounted on spindles 44 to which are secured sprocket wheels 45 which are connected with the sprocket wheels 46 on the shaft 47 by means of the sprocket chains 48. One of the spindles 44 may have an additional sprocket wheel, 49 secured thereto which may be connected with a sprocket wheel on a magneto 51 by means of a sprocket chain 52.

As will be found illustrated in Figs. 8 and 9 rings 53 are disposed in the cylinders 10 below the valve sleeves 18, the rings 53 being spaced from the valve sleeves 18 and having recesses 54 in which the gear wheels l0 and lO are disposed. In the top of the rings 53 there are inclined grooves 55 for conveying the lubricant to the gear wheels to and 40, the lubricant being fed to the inclined grooves 55 and the rings 53 from the inner sides of the valve sleeves 18, the lubricant passing from the bottom of the int'erior of the valve sleeves 18 through the opening between the valve sleeves and the rings 53 to the inclined lubricant grooves 55. The construction is such that the bottom of the pistons 28 move below the sleeves 18 to carry the lubricant into the space between the sleeves 18 and the rings 53.

Having thus described my invention I claim as new and desire to secure by Letters Patent:

1. In a device of the class described, two cylinders having ports, two valve sleeves, one disposed in each of the cylinders for cooperating with the ports, gearing on each of the sleeves, a spindle hollow at one end and journaled in a bearing between the cylinders, a second spindle disposed substantially in alinement with the first spindle and spaced from the hollow end of the first spindle, gears on the ends of the spindles meshing with the gearing on the valve sleeves, crank having an end disposed in an open end of the first spindle, and with a second end secured to the gear on the second mentioned spindle, a piston in each cylinder, a piston rod having means for operating the crank and articulated to one of the pistons, and a piston rod articulated to the other piston.

2. In a device of the character described, two cylinders having ports, two valve sleeves, one disposed in each of the cylinders for cooperating with the ports, gearing on each of the sleeves, spindles, gears on the spindles meshing with the gearing on the sleeves, pistons in the cylinders, piston rods articulated to the pistons and means operable by one of the pistons for rotating one of the spindles.

3. In a device of the class described, two cylinders having ports, two valve sleeves one in each of the cylinders, two pistons one in each of the cylinders, a shaft having two cranks, piston rods articulated to the pistons and to the cranks, gear teeth extending from each of the valve sleeves, a spindle journaled between the cylinders substantially at right angles to the cylinder axes and extending to each cylinder, a gear at each end of the spindle at the cylinders, the gears meshing with the gear'teeth on the sleeves, a second spindle having an end disposed at one of the cylinders, a gear at the said end of the second spindle meshing with the gear teeth on one of the sleeves, and means operable by a piston rod for rotating the second mentioned spindle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HUGO C. WELL.
